The workpiece is placed between the four sliding self-centring jaws of the mobile mandrel. Owing to their design, the jaws do not require claw replacement. The fixed mandrel itself, which consists of a solid structure where four self-centring idling rollers are accommodated, does not require tool-changing.

The FL 400 3D is built to guarantee the maximum degree of precision, quality and productivity for the laser cutting of tubes from 40 to 406 mm diameter. The machine allows tubes with a maximum length of 14000 mm to be processed. The tubes which can be loaded using a bundle or chain system, and the machine offers a host of machining possibilities owing to linear motors on 5 work axes and to a 3D cutting head.

The FL600 3D was conceived to work on tubes with round, square and rectangular sections, which are loaded automatically with a tube loading system from a bundle, while the open section profiles are loaded with a chain loading system. The Work range is 90 to 610 mm diameter, for tube lengths up to 14000 mm and more. The “heart” of the plant is a tri-dimensional system called “Sphera” which enables any point in a spherical space to be machined: movement is along 5 interpolated axes, with recirculating ball screws and linear motors.

Revolutionary plant for in-line laser cutting of tubes. It can be used for any profile with diameters of up to 220 mm and more. It overcomes the great drawbacks of the traditional cutting systems still used in today’s production of welded tubes. High cutting quality, absence of burrs and cooling fluids, noiseless operation, and no need for machine downtime for frequent tool changes are the distinctive features of this innovative plant.
